'Metal' in the Bible

And I looked, and, behold, a stormy wind came out of the north, a great cloud, with a fire infolding itself, and a brightness round about it, and out of the midst thereof as it were glowing metal, out of the midst of the fire.

And I saw as it were glowing metal, as the appearance of fire within it round about, from the appearance of his loins and upward; and from the appearance of his loins and downward I saw as it were the appearance of fire, and there was brightness round about him.

Then I beheld, and, lo, a likeness as the appearance of fire; from the appearance of his loins and downward, fire; and from his loins and upward, as the appearance of brightness, as it were glowing metal.
